Why does my email look good in Outlook, but not in other email programs?
Microsoft Outlook tends to display emails correctly in most cases, overlooking design and other issues. For this reason, don't use Outlook as your standard when testing emails. Test your campaigns with other email clients, such as Yahoo! Gmail, AOL and more, just to verify how it would appear when sent to recipients with these email clients. Find out more on how to verify how your email will appear to recipients using various email clients.
